Ellie must mix 6 tablespoons of plant food for every 2 gallons of water. if she has 6 gallons of water, how much plant food should she use?

1 gallon of water = 3 tablespoons of plant food
6 gallons of water = 6 x 3 = 18 tablespoons of plant food.
So your answer is 18 tablespoons of plant food.

Well for every 2 gallons she needs 6.
First we need to find the unit rate. It basically tells you how many tablespoons you need for 1 gallon. If we know this we can find out how many we need for 6.

to do that simply divide the 6 by 2 to get 3. The 3 means she needs 3 table spoons for 1 gallon. we need 6 gallons so multiply 6 by 3. 6x3= 18

she needs 18 tablespoons for 6 gallons.

hoped this helped :)
